1. A wearable optical system, comprising:
a user wearable band frame having a front region and a back region and adapted to encircle a head of a user and a visor portion secured with the band frame, wherein the visor portion comprises lenses and a centered viewing portion comprising a display that is directly viewable by the user via a horizontal optical path defined relative to an eye of the user such that the display is viewable by the user when wearing the band frame via the horizontal optical path, wherein the horizontal optical path refers to the optical path from the eye of the user looking straight out in an eyes-centered orientation, wherein the band frame is secured with the visor portion, and the lenses comprising a first lens and a separate second lens each corresponding to a different eye of the user, and the first lens and the second lens are separate from and positioned a distance from the display wherein the display is non-transparent and is visible by the user through the first lens and the separate second lens;
a vision redirecting mechanism comprising a camera wherein the vision redirecting mechanism is cantilevered or comprised in or attached to an imaging extension of the visor portion or the centered viewing portion and extending a preset distance forward of the band frame and above or within the horizontal optical path, defining a work area optical path, wherein the camera is in optical communication with the display and communicates images to the display, the horizontal optical path and the work area optical path being different optical paths and the work area optical path is oriented downward at an angle relative to the horizontal optical path, wherein the camera or the centered viewing portion is configured to magnify an image passed through the work area optical path;
a shade cooperated with the visor portion and positioned relative to the display, and wherein the shade is configured, when in a first orientation, to limit outside light to eyes of the user;
a light source affixed to the visor portion and configured to emit a light signal, wherein the light signal is coextensive with the work area optical path; and
a power source,
wherein the display comprises a stereo display and is within the visor portion positioned aligned with the first lens and the second lens, and
wherein the wearable optical system is adapted to balance an overall weight of the wearable optical system between the front region and the back region, wherein the lenses and the centered viewing portion, the vision redirecting mechanism and the imaging extension are positioned relative to the front region and the power source is positioned in the back region;
a first shield secured with the band frame and positioned to be between the eyes of the user and the first and second lenses when the band frame is worn by the user;
side shields secured with the visor portion;
wherein the visor portion is pivotably secured with the band frame, separately movable from the band frame and configured to be translated between a working position to a retracted position about one or more hinges;
wherein the shade is opaque, positioned proximate a peripheral portion of the visor portion, and movable between the first orientation that limits outside light to the eyes of the user and a second orientation that permits at least some outside light to pass to the eyes of the user; and
wherein the side shields are secured along portions of respective sides of the visor portion to be positioned, when the visor portion is in the working position, along a portion of sides of the head of the user and lateral of a respective one of the eyes of the user in a peripheral view of the user extending away from the visor portion toward a visible work area when the user wearable band frame is worn by the user, and wherein the side shields are movable away from the eyes of the user when the visor portion is in the retracted position.
